To enhance platform resilience in cases where internet service has been compromised, we have added a new field to the TWS and IB Gateway login box, Name Resolution, which allows you to bypass the normal DNS system you use when logging in, and access internal mapping instead. This will allow you to log into and trade your IB account even when normal internet access is impaired.
To use this emergency feature, from the Login box click the "More options" link in the bottom left corner to expand the interface. From the Name Resolution box select IB Only. This process should only be used when needed as it will result some non-essential services, for example Risk Analytics, being unavailable.
